Definitions

  • Plant for storage of storage energy and method for producing such a plant Plant for storage of storage energy and method for producing such a plant
  • the invention is based on the problem to provide a system for storing energy storage and a method for producing such a system, which is suitable for storing large amounts of energy to the order of magnitude of the daily needs of a country such as Germany and low cost per stored energy unit and low Ver - Wear of the system brings with it.
  • This problem is solved by a system for storage of energy storage according to claim 1 and a method for producing such a system with the features of claim 6.
  • Advantageous embodiments of the invention are the subject of the respective dependent claims.
  • a system for storing potential energy has a hydraulic cylinder, a mass to be lifted and a sealing ring on the edge of the mass to be lifted, so that it is ensured that at least one point of the space between the mass to be lifted and the facing inner wall of the hydraulic cylinder against a Passage of hydraulic fluid, in particular water, is sealed.
  • the mass to be lifted thus forms a piston which is guided in the hydraulic cylinder.
  • the hydraulic cylinder may also have a cross-section that avoids the circular shape. Appropriately, however, over the length of the hydraulic cylinder in the direction between the earth's surface and the center of the earth seen constant cross-section to avoid wedging a mass to be lifted in the hydraulic cylinder as possible.
  • the mass to be lifted is a rock mass represented by a cut out rock, that the hydraulic cylinder is formed by the cavity between surrounding rock and the cut out rock, and that the cavity is sealed by the sealing ring to the surrounding rock.
  • the mass to be lifted and the hydraulic cylinder "worked from the solid" are.
  • any density fluctuations of the material within the volume of the mass to be lifted are compensated for by placing ballast agents on the face of the mass to be lifted, which faces the atmosphere, i. the upper side, which originally formed part of the earth's surface, are arranged.
  • ballast agents on the face of the mass to be lifted, which faces the atmosphere, i. the upper side, which originally formed part of the earth's surface.
  • water tanks can be used as ballast. In this way, a tilting of the mass to be lifted in the hydraulic cylinder, which could hinder the movement of the cylinder can be avoided
  • a particularly good seal is achieved in a system for storing potential energy, in which the sealing ring is formed by a circumferential circumference of the mass to be lifted cone, in which a cylindrical joint is inserted, which carries a lamella provided with a sealing bead.
  • the sealing bead is pressed against the surface of the wall of the hydraulic cylinder and thus achieved a seal.
  • Particularly preferred is because of a particularly good seal at high pressures an embodiment in which a dense, flexible material is attached to the underside of the lamella, which conclusively closes with the sealing bead and the mass to be lifted.
  • the method according to the invention for producing a system for storing positional energy comprises at least the following steps: a) sinking a shaft, which has at least one depth H, below the earth's surface.
  • the depth H corresponds approximately to the length of the mass to be lifted in the working direction, ie in the direction between the earth's surface and the center of the earth.
  • this shaft which is to serve as a supply and transport shaft for the later work, as a rule expediently lies outside the region which later forms the mass to be lifted.
  • the depth H does not necessarily have to be achieved in a single step, but it is also conceivable that further process steps are carried out after sinking a section before or simultaneously with the sinking of another section. Of course, several such shafts can be sunk, for example, to reduce transport routes.
  • the steps d) to f) thus serve to provide the side surfaces of the hydraulic cylinder and mass to be lifted. g) Pass horizontal boreholes from the tunnel to the center of the hydraulic cylinder. h) smashing of the rock at the bottom of the hydraulic cylinder, so that there is no longer a firm mechanical connection between the cylinder bottom and the reciprocating piston.
  • the bottom surface (ie the underside) of hydraulic cylinder and mass to be lifted is created.
  • At least one further horizontal lug is driven at a depth which is smaller than H, and leads to the point at which the wall of the hydraulic cylinder is to lie.
  • a parallelization of the work steps can be achieved in particular by using several rock saws in different holes simultaneously when performing steps e) and f).
  • step h offers a blast. It is particularly desirable to achieve the most homogeneous possible weight distribution of the mass to be lifted. Therefore, it is convenient to perform a survey of the surface of the mass to be lifted created by a gravimeter.
  • the invention is based on the basic idea that a large mass of rock is lifted by a hydraulic system, wherein the mass to be lifted is represented by a preferably cylindrically cut out rock.
  • the hydraulic cylinder is the resulting cavity between the surrounding Rock and the cut out rock. This cavity is sealed by a sealing ring at the edge of the mass to be lifted against the surrounding rock.
  • the cavity is filled via a high-pressure pump and a connecting lug between the pump and cavity with water from a reservoir.
  • potential energy potential energy
  • this potential energy can be taken from the fact that the pressurized water is conducted via the connection tunnel and via a turbine, as usual in pumped storage power plants.
  • the advantage of the invention is in particular that the cut rock mass grows in the cube of the system radius, the cut surface which causes the main manufacturing costs, but grows only in the second power with the system radius. This follows from the equation for the lateral surface M of a cylinder whose height h corresponds to the cylinder diameter:
  • the maximum stored energy is calculated from the density of the rock pi and the effective density p 2 , which has to be considered due to the hydrostatic situation, since water with the density p 3 replaces the rock mass.
  • the system radius is the radius r of the cylinder

  • Fig.4 A detailed representation of the procedure when sawing the mass to be lifted from the rock
  • FIG. 5 shows a detailed view of the structure of a sealing ring for such a system
  • Diameter d out in a cylinder 2 which was formed by the excision of the reciprocating piston 1 from the rock.
  • a seal 1b is placed at half the distance h, ie at the height h / 2.
  • water is fed into the cylinder 2 with a pump 8 from the reservoir 9 at the point 4 via a line system 5 and 6.
  • the surface 3 should represent the earth's surface. Is the Lifting piston in the raised position (lifting height) D, so at any time by the hydrostatic pressure water via a turbine 7 back flow into the reservoir 9 and thereby produce electricity in a generator 7b.
  • the mass m must be as large as possible.
  • the lifting height D can not be freely selected as it must be smaller than half the cylinder length h, otherwise tilting of the lifting piston can occur.
  • a well 30 is sunk below the surface with a depth H below it.
  • two lugs namely a lug 32 in the depth H and a lug 31 in the depth H / 2 are driven horizontally to near the planned cylinder wall 2.
  • circular tunnels 35 and 36 are driven into the mountain with a diameter corresponding to the diameter d of the later lifting piston 2.
  • the tunnel pieces 5 and 4 are driven from Figure 1 to reach the bottom of the cylinder 2, through which the water can be fed into the cylinder.
  • the tunnel 35 in FIG. 2 secures the sealing ring 33 to the lifting piston.
  • the connecting lugs 31 and 32 are sealed watertight. Now 8 water can be fed via the pump and thus energy stored.
  • FIG. 5 illustrates a sealing ring 33 with a preferred construction which can compensate for unevenness of the wall of the cylinder 2.
  • a cylindrical joint 53 is inserted in a circumferential around the entire piston 1 cone 52, which carries a blade 54 which presses against the surface 57 of the cylinder wall 2 due to the water pressure 58 with a sealing bead 55 and thus seals the piston 1 against its environment ,
  • a dense flexible material 56 can be attached to the underside of the sealing lamella, which closes conclusively with the bead 55 and the piston 51.
  • the louver 54 exhibits a one-dimensional mechanical behavior due to the long length, which may be several kilometers.
